This view combines more than 400 images taken during the first several weeks after NASA's Phoenix Mars Lander arrived on an arctic plain at 68.22 degrees north latitude, 234.25 degrees east longitude on Mars.

Clouds of dust and ice swirl past the Surface Stereo Imager (SSI) camera on NASA's Phoenix Mars Lander in this frame from a series of images taken on the 132nd Martian day of the mission (Oct. 7, 2008).

This frame from a series of images shows NASA's Phoenix Mars Lander's telltale instrument waving in the Martian wind. Documenting the telltale's movement helps mission scientists and engineers determine what the wind is like on Mars.

This frame from an animation shows the movement of several dust storms near NASA's Phoenix Mars Lander. These images were taken by the lander's Surface Stereo Imager (SSI) on the 137th Martian day, or sol, of the mission (Oct. 13, 2008).

This anaglyph was taken by NASA's Phoenix Mars Lander's Surface Stereo Imager Oct. 7, 2008. The anaglyph highlights the depth of the trench, informally named 'La Mancha,' and reveals the ice layer beneath the soil surface. 3-D glasses are necessary.

The Surface Stereo Imager camera aboard NASA's Phoenix Mars Lander acquired a series of images of the laser beam in the Martian night sky. Bright spots in the beam are reflections from ice crystals in the low level ice-fog.

The robotic arm on NASA's Phoenix Mars Lander enlarged a trench beside a rock called 'Headless' on Sept. 20, 2008 in preparation for sliding the rock into the trench. 3D glasses are necessary to view this image.

This image from a sequence of images that combines 32 images of clouds moving eastward across a Martian horizon. The Surface Stereo Imager on NASA's Phoenix Mars Lander took this set of images on Sept. 18, 2008,

As NASA's Phoenix Mars Lander excavates trenches, it also builds piles with most of the material scooped from the holes. The piles, like this one called 'Caterpillar,' provide researchers some information about the soil. 3D glasses are necessary.

A laser beam from the Canadian-built lidar instrument on NASA's Phoenix Mars Lander can be seen in this contrast-enhanced image taken by Phoenix's Surface Stereo Imager on July 26, 2008, during early Martian morning hours of the 61st Martian day.
